Document Summary
Reduce stress and stain on muscles, joints, ligaments, and soft tissue. Promote and maintain proper body control and balance. Lift techniques: principles of proper body mechanics. Visualize and physically plan the activity before attempting it. Position yourself close to the object to be moved so that you can use short lever arms. Maintain your vertical gravity line within your base of support to maintain stability and balance. Position your center of gravity close to the object"s center of gravity to improve control of the object. Tighten your "core" muscles before beginning the lift; use the major muscles of the extremities and trunk to perform movements or activities, and maintain your normal lumbar lordosis. Roll, push, pull, or slide an object rather than lift it. Avoid simultaneous trunk flexion and rotation when lifting or reaching. Look straight ahead and do not twist or turn your body while lifting. Take your time and lift the item with smooth motion; avoid jerking movements.
